This is hilarious. A BBC reporter was supposed to interview one Guy Kewney on some technology issues (the Apple vs Apple lawsuit in the UK), but when they called "Guy" to the studio, the wrong one showed up.
Look at his face when she starts asking some questions...
BBC recognised the error and posted about this, later:

Guy Goma, a graduate from the Congo, appeared on the news channel in place of an IT expert after a mix-up.
But Mr Goma, who was wrongly identified in the press as a taxi driver, was really at the BBC for a job interview.
Mr Goma said his appearance was "very stressful" and wondered why the questions were not related to the data support cleanser job he applied for.

I imagine this could be really stressful for Mr. Guy Goma, but I think he did well with his answers. Probably better than some "experts" would.
What really surprises me is this happening on BBC. Can't we trust any news source anymore?
